Medicaid paid $3,469 for 42 billed services this clinician did in 2021, up to 15 people in a month for one service.
Medicaid and CHIP claims where this clinician did the service, fee-for-service and managed care together. Any month with fewer than 11 patients is hidden, so small Medicaid practices undercount.
